Using a user defined class vector inside the class file

I have a class called Account with below parameters:

Account::Account(string ibanCode, string paramOwner, double amount) {}

I have created a vector consisting of class Accounts inside main function:

accs.push_back(Account(fullName, iban, value));

I want to write a function to print all the Account values in my vector by a class member function called displayAll() , and so far I tried this:

void Account::displayAll() 
{

  for (int i = 0; i < accs.size(); i++)
  {
    cout << accs[i].displayBalance() << endl;;
  }
}

And I want to write it inside the class file. Do you have any suggestions?

I think making it a member would be extremely complicated, the best option should be using a normal function that can access the parameters.

    #include <iostream>
    #include <vector>
    
    using namespace std;
    
    struct Account {
        Account (string ibanCode, string paramOwner, double amount) : _amount(amount), _ibanCode(ibanCode), _paramOwner(paramOwner) {};
        string _ibanCode;
        string _paramOwner;
        double _amount;
    };
    
    void DisplayAll (const vector<Account>& Accs) {
        for (const auto& Acc : Accs) {
            cout << Acc._ibanCode<<' '<<Acc._paramOwner<<' '<< Acc._amount<<'\n';
        }
        return;
    }
    
    int main () {
        vector<Account> Accs;
        Accs.push_back(Account("SomeCode", "SomeOwner", 2.0));
        Accs.push_back(Account("SomeOtherCode", "SomeOtherOwner", 3000.42));
        DisplayAll(Accs);
    }

To avoid complicating the answer too much I made a struct but you can either make the DisplayAll function a friend of the class or make some getters.
